SPECIFICATION forming part of Letters Patent No. 397,690, dated February l2, 1889.

Application filed June 18, 1888. Serial No. 277,423- (No modela To all whom, it muy] concern:

Be it known that l, JAMEs B RADY, a Vcitizen of the United States, residing at Nauvoo, in the county of Hancock and State of Illinois, have invented certain new and useful Improvements in Corn-Plan ters; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable o1 hers skilled in the art to which it appertains to make and use the saine.

This invention relates lo agricultural implements.

The ob ject is lo plant corn or seed at predetermined intervals by means of a planter set on wheels to be drawn b v horses or other animals.

To this end my invention consists oi ya frame, a main axle carrying a mutilated cogwheel, and two driving-wheels, a cog-wheel and a cam-grooved pulley on a counter-shaft, and two seed-hoppers, an oscillating valverod actuated by a lever provided with a pin and friction-roller engaging the cam-groove in the pulley; also of a frame formed in two parts 'for thepurpose of adj ustment of ruim ers, a mutilated cog-wheel, a cog-wheel, and a canigrooved pulley, two sei-fiil-hoppers placed over perforated posts, a sliding valve-rod actuated by a lever provided with a pin and frictionroller engaging the cam-groove in the pulley, and a pawl-indratchet movement to cause the turning of the shaft affecting the mechanism for dropping the seed, a clutch for throwing out of engagement, the mutilated cog-wheel, with the main aXle, and sundry details of construction, to bc hereinafter described.

In the a-ccompanyilig drawings, forming part of this specification, and in which like letters of reference indicate corresponding parts in all the figures, Fi gure l is a plan view of my corn-planter. Fig. 2 is sectional view showing one of the drivin g-wheels, the mutilated cog-wheel on the main axle, the second cog-wheel on the counter-shaft carrying the cam-grooved pulley, the lever provided with the pin and friction-roller engaging inthe cam-groove and one ol' the seed-hoppers with part of the oscillating valve-rod connected to the lever. Fig. 3 shows the construction of the clut-ch `for throwing the mutilated cogwheel out of engagement with the main axle. Fig. 4- shows the pawl-and-ratchet device to prevent the backward rotation. of the drivingwheels affecting the mechanism `for dropping the seed.

In the drawings, A represents the frame, which is formed in two parts, one carrying the main axle B and provided with the crossrails o" o?, and the other carryin g the runners, and having the two cross-rails o1 o5 and the braces o rt'- to receive the tongue.

0n. the main axle .13, outside of the frame, is the drum l), having the iaiuflieix-l'eetli' b' formed on its inside surface.

C designates the driving-wheels, the hubs of which are provided with ratcliets and `i springs adapted to engage the ratchet-teeth in the inner surface of the drums l). On the axle B, inside the frame, is loosely mounted the mutilated cog-wheel. l), having the clutchteeth CZ in its side and the diainet-rically-opposite gear-teetl1v d di. I have shown. in the drawings three gear-teethv on one side and three on the other; but a larger number may be used when it is desired to increase the \d sown. This cog-wheel has a depressiomf in. its hub,near the axl.e,within the clutch-teeth, and the axle carries a pin, d1, moving in the depression. The axle has also a collar, (15,011 the other side of the cog-wheel, which, with the pin d4, prevents the cog-wheel from having any lateral motion on the axle.

E designates the movable portion of the clutch mounted on the axle, and which, by means of the spline e and feather e', receives the movement of the axle and transfers the said movement to the mutilated. cog when thrown into engagement by means of the bifurcated lever c2, pivoted at e5 in the arm. or bracket e, attached to the frame.

F designates the cog-wheel on the countershaft f, which is jonrnaled in bearings j" on. the frame. The shaft is preferably square, with round journals; but a round shaft may be used and the cog-wheel keyed to it. The cog-wheel F engages the gear-teeth of the mutilated cog-wheel, and has four of its teeth iilled, as shown in the drawings. This con struction gives greater strength to the wheel, and is permissible because of the other cogwheel being mutilated. On the same shaft,

IOO

f, is a pulley having on .its periphery a camgroove made of such a shape as to give two vibrations to the end of the lever operating the valve-rod ateach revolution.

G- designates a lever, fulerumed at g on the under-side of the cross-rail a2. On one end of the lever is a pin, g', and at the other end a friction-roller, g2, which engages with the cam-groove f2.

Il designates the valve-rod, having a projection, h, provided with a slot, 71,', in which moves the pin g of the lever G. At each end ol the rod are flat pieces, made either of metal or wood, which act as slide-valves in the hoppers.

K designates the hoppers, of which there are two, carried on a cross-beam, k', and provided with apertures communicating with vertical passages in the posts it.

L designates the forward portion of the frame, connected with the other part by means of the curved pieces Z', through which pass the screws 7:1, which hold the cross-beam 7s in position. On the forward part of the frame are struts l', to which are adj ustably secured the ends of the runners M by means of the screws m and nuts m and the holes in?. The runners M are secured to the ends oi the posts 763 in such a manner that the lower edge of the bottom of the runners will be on a line with the end of the post.

The operation of the planter isas follows: The mutilated cog-wheel having been thrown into operation by the clutch, at every halfrevoluton of the cog its teeth will engage the second cog-wheel, and thereby turn the camgrooved pulley as long as the teeth engage the teeth of the second cog-wheel, the lever will be vibrated by its pin and friction-roller moving in the cam-groove, and the valve-rod will receive an oscillating' movement from side to side, thus causing the valves and their apertures to cross the apertures in the base ol' the seed-hoppers and allowing the seed to drop down through the perforated posts. The distance between the seeds will naturally depend upon the number ot' teeth on the mutilated cog-wheel, for it is evident that the second cog-wheel will not be rotated, and there fore not actuate the valves, except when meshing the teeth in the other cog-wheel. When it is desired to turn round or to back, the pawls on the hubs of the driving-wheels will not engage the ratchets on the drums attached to the main axle, and therefore will not rotate the axle.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a seed-planter, the combination, with the axle, of the mutilated gear-wheel mounted loosely on the axle, the clutch adapted to connect the axle and mutilated gear, the second gear-wheel mounted contiguous to the first and rigidly connected to the wheel. having the cam-groove, and the valve-rod connected to and receiving motion from the second gearwheel, substantially as described.

2. In a seed-planter, the combination, with the axle, of the mutilated gear mounted loosely on the axle, the supporting-wheels, the pawls and ratehets connecting the wheels and the axle, the clutch connecting the axle and the gear, the second gear arranged contiguous to the lirst, the wheel having the cam-groove rigidly connected to the second gear-wheel, the sliding valve-rod, and the lever connected at one end to the valve-rod and having its other end projecting into the cam-groove, substang tially as described.

3. In a seed-planter, the combination ot' a frame constructed in two parts, one supported by the axle having the mutilated gear-Wheel and earryin g the second gear having the camgrooved wheel connected thereto, and the le` ver communicating mot-ion from the camgroovcd wheel to the valve-rod, and another part. carrying the hoppers and valve-rods, the two portions being connected by the angular joining-pieces, and the runners connected, substantially as described.

In testimony wh creol? l a llix my signature in presence of. two witnesses.
